Sigbjørn Skjæret (CISC) just released another version of VCDGear for MorphOS. This program allows you to extract MPEG-Streams from CD's, fix MPEG files, convert files and many more. Further information and the download link can be found on the Homepage.

In reply to Comment 2 (Joe):There are no .dat files on VCDs, at least the .dat files you see are not really there; read the documents about how the VCD standard works.
For VCDGear you need to extract the MPEG-Data either with a tool or a CD filesystem that supports reading the not-so-real-dat-files. VCDGear itself does nothing to the disk.
